Quick poll. Which of these PSUs should I buy?

OCZ

or

Corsair

Ignoring the 'This Week' offer price as I won't be buying yet, and the few quid difference is not an issue. I just want the better PSU.

Or something else? I don't have big power requirements, just one HDD etc. My graphics card is and always will be mid range, no SLI etc.
 
Hhm. I know my power needs aren't great, but 500w seems a bit low. My current card is a Nvidia GTS 250. I will upgrade at some point to the £150 ish equivalent.

XFX as a brand name makes me wary for some reason. I'm sure I used to read of bad reliability and poor customer service.
 
500watts is fine for a GTX250 and an equivalent £150 GFX card (ATI 7850)

The XFX is made by Seasonic.
 
The OCZ for sure, only Corsair PSUs worth buying are TX/HX/AX series. Also checkout the BeQuiet Pure Power L8 630w which is semi modular or OCZ ZT/Antec HCG-620M as well which are fully modular.

Don't Coolermaster power supplys are garbage.

HEEEELL no they are not! The coolermaster silentpro gold 1200watt PSU I've had for ages is flawless.

My corsair HX1000W popped after 18 months taking out a motherboard and somehow also a Crucial SSD too when I plugged in a second gtx480.

The Silentpro gold gets my pure perfection seal of approval having ran 3 gtx480s in sli with a massive overclock on all and the processor and about 8 harddisks solid until I went for an x79 upgrade a couple months ago.

I experienced less noise from the soundcard with the coolermaster too. Own a coolermaster, kill something with a coolermaster before you spout bias against a great company.
 
I suggest:

YOUR BASKET
1 x Corsair HX 650W ATX Modular SLI Compliant Power Supply (CMPSU-650HXUK) £89.99
Total : £100.49 (includes shipping : £8.75).




I have the slightly smaller 620w version of this and have run it in a heavy use PC for 6 years straight. Its awesome.

I am a big corsair fan because of that fact, and I know I am not the only one. I know other manufacturers are probably just as good, but for me it would have to be a corsair.

Corsair are good but you might as well go with the Seasonic ones since they make the Corsair ones and now have a brand new range ( G series and X series out)

If 550w can power crossfire, why do people need / buy 1200w PSUs?? Surely even the high end cards don't need that much power.

Because they do tri/quad SLI/Crossfire.

The 7850 only needs an additional 6pin PCI-E connector as well as the power it sucks from the actual PCI-E slot, higher end cards need two additional connectors (2X6pin, 2X8pin etc)

They have a lot of drives+fans.

Remember its best to run a PSU at around 50-60% load from what I read at Jonnyguru/hardware secrets.

Er, I wouldn't. I've had 2 Corsair PSU's fail on me (both were HX models) & 3rd time wasn't a charm. I'd wait for the Seasonic G series to come into stock TBH, If not go for the XFX as stulid suggested. :)

Xfx is the other brand I've had some experience with, very stable and no problems yet running 2 years quietly in my gfs pc.
 
Okay, so it's a choice between the XFX 550w and the OCZ 650w. Why should I go for the XFX? Wouldn't the 100w extra be a better choice?

HX 650 - Seasonic
Seasonic G - Seasonic
XFX - Seasonic

Notice the pattern? :)

PSUs can fail for many reasons, a lot can be down to the equipment and supply it's being used with, failing can be the built in protection on the PSU doing it's job.

More importantly did the build in protection stop any damage to your PC?

Anyway all 3 PSUs should be fine. Failure is always a possibility with any PSU, the best ones are designed to fail and stop working before taking out your PC. :D
