Are these PSUs any good?

If it's a powercool..... another website lists the 12v rails as being between 1-14, and 1-16amps. 30 amps across the 12v rails isn't too shabby, but the worrying thing is they don't exactly commit themselves to that number, giving it as a range from 1-14.

Comparitively, the corsair tx 650w offers 52amps on it's single 12v rail.... it's almost twice as good.
 
The wattage rating on the box is an amalgamation of the different rails within the PSU. The most important one is the 12v rail, which powers the CPU and graphics. However, it is quite easy to increae the available ampage on the other rails to result in the same wattage rating, even with a weaker 12v rail. The Corsair 650w unit has more amps on the 12v rail than the OCuk, uses the reliable CWT base and has an extended warranty. The OCuk ones are made using Powercool, which do not provide particularly stable power, and have a lot oscillation in the rails.

This isn't gobbledegook mate, PSUs are one of the few things on the market where you do actually get what you pay for. IF you put that PSU in a high end machine, you have a much higher risk of damaging your components due to oscillation during load and the risk of the PSU blowing due to dodgy overvolt protection.
 
Even some branded arent that good tbh. Use a site like http://www.hardwaresecrets.com/ and see its not as simple as brand = good.

Yes there is a diff between top notch and average, and the super cheapo supplies are probably a risk.
Some quality ones have some components vastly overspecced, extra components etc, but not all do.
Previously I vastly overlooked the importance of a power supply, after you review that site and look at some of the horrors it makes you realise.
 
^^ Yup, there's no real standards when it comes to rating psus. The current can be manipulated by altering the temperature. They can rate a psu as producing a certain current, whilst they're cooling it to -10c...... put that on the label, when it won't produce anything like that current at a sensible operating temperature of around 30c or so.

They can also just put the peak output on the label, instead of the sustainable output.
 
Thanks for the answers, all i was really looking for was if i could trust the OcUK ones. Im fully aware of the risks in a PSU and why you should get a quality branded one, since OcUK seem like a reputable company i was hoping there PSUs might be worthwhile. Ill most likely be powering a Phenom2 system with a gtx 470.
 
This thread has just re-affirmed what I thought about some of the advice I've seen you giving other people, I dont mean to be harsh, but if you dont know what you're talking about you really shouldn't be trying to advise other people

Is that supposed to be aimed at me? so you'd you be happy to advise someone to buy a cheapo psu to power a high end gaming rig, even though said psu's have been proven to be not that brilliant and really only intended for office type machines.

So if you are happy to advise that im certainly not, especially for a key component like the psu.
 
Excuse me? I don't say anything without having some knowledge in it mate all im asking here is are the OcUK brand PSUs worthwhile whats the problem with that?

If you have a problem with me not being a fan of SSDs and IPS monitors thats cool but i stand by my opinions and i HAVE seen and tried both.

Is that supposed to be aimed at me?

No mate hes defiantly having a dig at me, ive stated before i don't think SSDs and IPS monitors are worth the money which 95th dissagrees with so apparently i don't know what im talking about.

Just to clarify Bifday, no it wasnt aimed at you, it was aimed at OP (Gantoris) I dont mind people having different opinions, thats all well and good and is the point of these forums, however some of them seem "strange"
I have agreed with you in the past that when building a gaming build on a budget the OP should not include a SSD or IPs monitor, what I dont agree with are instances of you recomending someone spend £550 on gfx cards and £160 on monitor, I accept that not all people like IPs and some would prefer 120Hz, not a problem, youre right I do personally like IPS, but the above instance is an example of a strange recomendation, theres been others, and before you ask no I wont go through and name them all,
I really wasnt trying to have a go at you personally, Im sure there are things you do know about, and Im in no way trying to suggest Im the font of all knowledge, again this forum is for discussing opinions, however this thread has shown a certain level of ignorance, imo, and thats why I posted my previous comment, Im not going to start getting into an argument with you on this
 
I don't particularly want to argue either, you've seemed like a stand up guy to me so far but i fail to see why asking if the OcUK brand PSUs are any good shows ignorance (im completely unfamiliar with them). I plan on getting a 500w OCZ but was curious about OcUKs own brand, i really don't see the problem here.

And if someone says to me they want a system specifically for gaming then i feel the budget is best spent in the GPU i don't see the problem with that, to me from experience a mid range monitor such as the Ilyamas are just fine. I understand and respect people who are crazy about the best audio/visual equip cause as ive said before i have a friend who is mental for that kind of thing but for me personally the ends don't justify the cost and frame rates are all that count.

its probably other stuff like recommending a AMD 955be cpu when the someone has a 940be CPU already that doesn't help.

or selecting a Nvidia GPU with a 890GX chipset motherboard.

or recommending a Hanns.G monitor when there are plenty of better ones on special offer.
 
Dont recall the 955/940

The guy specifically asked for an Nvidia GPU and your ignoring the rest of that thread which explains this and the OP was quite happy with what i recommended.

Nothing wrong with Hansg, which is a matter of opinion. My brother has the 27.5" and i like it.


Dont see the point in this mate, ive no desire to get into a slagging match all i wanted to know was if the OcUK PSU was worth a look. If you dont like me i think i can survive.

at the moment i'm running

sapphire HD4850 512mb
Phenom II 940 @ 3.0ghz stock (deneb)
250GB HD
430W PSU (think it's barely alive as it is)
Biostar 790GX (im pretty sure that's it, bare with me)

forgot, 4GB Kingston DDR2 1066Mhz iirc

Have you considered trying AMD? The Phenom 2s are nice lil CPUs and offer you a lot of bang for your money, if gaming is your thing you wont notice any difference between a Phenom2 and an i5. And the Black editions such as http://www.overclockers.co.uk/showproduct.php?prodid=CP-244-AM&groupid=701&catid=6&subcat=1328 are an overclockers dream giving even more value. Not only is the CPU a lot cheaper but the mobos for AMD are much much cheaper and tend to be rich with state of the art features such as USB3 and Sata3.
