a friend of mine (hobgoblin73) is looking to buy a computer his local shop has offered him. (thread here)

it all looks perfectly ok, except for the power supply, which for a big rig like this i would personally rate as the most important part, and worth putting money into, but i cant seem to get that into his head.

the power supply in question is an 800W modular power supply from Evo Labs. it is very hard to get any technical details about it whatsoever. this is all i could find about the model i suspect is being used.

so what im really asking is, will this power supply be a good choice if its going to be powering the following rig until it cant keep up, which should be many years

what it will be powering:
- intel i7-2600K @ 4.6Ghz
- 2x MSI ATI Radeon 6970
- foxcon P67A-S Motherboard (B3 revision)
- corsair H70 CPU cooler
- 1x HDD SATA 6GB/s (maybe one or two more in the future, not sure)
- LiteOn iHOS104 Blu Ray Drive DVD-RW Multidrive
- a few case fans.


also, will it actually have enough power connectors? i see it only has 2 PCIe 6 pin power connectors, so it will need 4x 4pin connectors to compensate for those with the converter cables you get as standard.


thanks for any help
 
a cheap PSU is inefficient so a lot more electricity is rquired in comaprison to a high end PSU. Also cheap psus tend to be very light because they don't have adequate heatsinks built in, and need to be cooled by a FAN spinning ridiculously fast.

Thereby making it very noisy, and bad for your ears as well.

A high end PSU will "pay for itself" in electricity cost savings and also stop you from going insane from the constant noise

hmm, didnt think of the energy savings.

hopefully this will stop him thinking 'well, it might be alright' and make him get a better one
 
Get that PSU, smash it to smitherines and send it to PSU hell! :)

Something like the XFX, or an Antec modular, or if you really want top quality the AX series from Corsair

Its not the price, but rather the build quality. I personally have a corsair and they are quality units, silent, built to last, and if they do go pop, don;t destroy the rest of the PC.
The EVO Labs will be a cheap PSU, priced to make you think its a better one than it actually is.
 
The way that independant stores use poor unbranded units is crazy.

I would not power a watch off of one, let alone my £2000 PC.

Get a quality branded PSU.

Heres the psu in the Mosasaur http://www.overclockers.co.uk/showproduct.php?prodid=CA-047-OC

Not much of a price difference is it? How come this computer doesnt have a £100 psu in it if they are so good

the small difference in price is because the unit being offered by the computer store is modular, and this one is not. a modular PSU comes with some power cables being completely detachable, so you wont have a large amount of wire spaghetti wedged in the case somewhere. generally non modular 700-800W PSU's are around the £70 mark, whereas modular 700-800W PSU's are at the £100 mark. the good ones anyway

And as regards "but i cant seem to get that into his head" Thats a bit bloody cheeky isnt it. No need to speak to people as if they are thick.
Cheeky kids.

well, several times when you were talking to me you have said that you might just go for the cheap PSU and see what happens, despite not knowing if it was any good. so i think im justified in my remark, especially since, if its a bad PSU, it could end up costing you £750 if it takes other parts with it when it dies.

aslo, you say theres no need to talk to you as if your a kid, but you talk to me like im one. im 19, which means im an adult as well.

i'll leave the rest of this discussion for the private chat in the trials forums, because arguments and insulting matches isnt what a public forum is for

Here's a prime example of why you don't buy a cheap psu.

Yesterday one of my neighbours asked me to have a look at her pc which had stopped working. She got it from a local pc shop last year and cost her £650. They saw her coming big time. Spec is a Athlon ll X4 630, 2Gb (single stick!!) of cheap unbranded ram, budget MSI K9N6PGM2 motherboard, 256mb 8400GS, Lite-on DVDRW, 320GB 7200.10 hdd and the cheapest crappiest case you have ever seen. No intake fan, in fact not even anything resembling a vent in the front and only a single 80mm exhaust. Nestled in the top was a Mercury psu suggesting it could output 400w. Yeah right!!

Dead as a dodo so unbolted the psu from the case to find it weighs practically nothing. Seriously, this thing was so light i though it must be empty. It was stinking too. That horrible burnt electrical smell. Looking through the fan revealed several burn marks inside so it was obvious that the psu had blown. After some close inspection the board is dead and so is the graphics card probably due to the pci-e slot looking like it has caught fire. On top of that the hdd is also dead so all she has that works is the cpu, ram and DVDRW. PSU blew and sent a power surge to the mobo maybe?

I asked her what she wanted doing and she said to put it all back together and she will take it to the place she got it from and demand that they get it sorted as it's (just) within the year since she got it. Anyway, she is taking it back on Monday and is going to see what they say. Personally i don't hold much hope for her without a fight as they are a right bunch of cowboys.

Morale of the story? Know what you are buying and do not, under any circumstances buy a cheap psu!!
 
Hmm I see what you mean.
This shop has been in my town for 15 or more years tho and they seemed fair when fixing my laptop last week.
Most I can go for this new rig is £1600, shall I just get the Mosasaur with the crossfire and be done with it. I want the most powerful gaming rig possible for this sort of cash.
I dont fancy building my own again now my dad isnt here to help anymore :(

Im just worried about buying something off the net and not being able to get any out to look at it if it starts acting up see.
 
The place she got hers from has been around for 15 years or so as well. Time established means nothing when you are selling to people who are completely clueless when it comes to the inside of a computer.

The Mososaur is a very good spec computer and you will have the peace of mind of buying it from a reputable retailer.

To be honest, the specs look good, only the PSU is dodgy. Maybe you can work out a deal to have them install a Antec / Corsair 850W -> 1000W. Oh and the case, I don't know. Must have some good air cooling as well. These 580's / 6970's will be cooking
