Which Psu to go for?

Scottwinning · Jan 5, 2014

What psu?

So I'm verry much an amature builder, just a media pc for music, video and the odd game of fifa battle field 3....

I have the following:

Asrock 970 Extreme 3 MB
Phenom 965 BE (stock cooling - not OC)
8GB DDR3 Ram
60GB OCZ SSD (used only for Windows 7 ultimate OS)
1TB HDD (media / games storage)
250GB HDD (other programmes)
Sapphire HD7790 OC GPU
DVD RW - not sure manufacturer (from an old pc)
2 x 80mm case fans

So made a schoolboy error and never considered the PSU! Just ran with a cheapo stock 500w PSU which came with my origional case.
Anyway when I upgraded from a HD5450 to the HD7790oc everything ran like a dream for a few hours, watching a film, then I stuck on BF3 to see what frames rates I'd get and POP everything just shut off after around 10minutes.
No Big Bang or anything just OFF.
I admit I used a molex splitter to power the GPU via a 6pin as I didn't have a spare way, should have rang alarm bells!

So I hope it's just the PSU that's fooked and I'm about to buy a new one to see what's salvageable, any suggestions?

Looking at:
Corsair CP-9020048-UK Builder Series CX 600W Power Supply (PSU)

Thanks in advance for your knowledge.

I would consider an XFX Core Edition 550W, it's higher quality than Corsair CX.

Thanks for your response Sakkura I'm aware from other posts the ???wattage isn't really the deciding factor and the quality is something more to be considered.
If I want to crossfire and other HD7790 in the future would this stand up?
I've tried a couple of psu selectors and get varying results from 500w-650w I think currently I'm pulling about 485w?
I'm in the UK to so cost varies significantly dependant on manufacturer to what you'd pay in the states.

Will Crossfire 2 7790's and made by the best in the power supply business SEASONIC.

Any others Blackbird?
Could maybe stretch to that but it's discontinued at most retailers on this side of the pond and I'd like to shop around for a deal ;-)

The XFX Core Edition 550W will crossfire 7790s fine. They use 85W and a 6-pin power connector each. The XFX has the connectors and plenty of power.

The Antec HCG 620W is a slightly scaled-up version of the same power supply design (Seasonic S12II).

Ok guys, thank you both so much, dilemma now is 600b with 3 year warrantee or xfx550 with 5year.

Both in price range (£50), which is better?

Dark Lord of Tech · Jan 5, 2014

Go with the SEASONIC made XFX 550W. , IT'S THE BEST 550 to 600w. ON THE MARKET.
