Gigabyte 560 ti 448 core

Hi all,

If I could please get some of your expert (in my eyes!) opinions I would very very much appreciate it :)

I bought a Gigabyte Geforce GTX 560 ti 448 core graphics card (http://www.ebuyer.com/320845-gigabyte-gtx-560-ti-448-core-edition-1280mb-gddr5-dual-dvi-hdmi-gv-n560448-12i) which was delivered this morning.

It led me to believe that my PSU (Trust 570W - PW-5500) was enough to power this monster as well as my rig.

My rig is:

i5 2500k cpu
16gb Ram
60gb OCZ Vertex 2 ssd
creative xfi extreme gamer soundcard

However, when I installed it this morning, I went to do the Windows Experience test to see what the score went up to. It ran for about 30 seconds and then crashed the PC into a restart. Tried it again and it did the same at the same point.

I tried skyrim and it detected the new settings and auto set them to high. Once my savegame was loaded the PC crashed and restarted within 30 secs of playing skyrim.

A quick google search seemed to suggest that it's due to a PSU issue.

I'm down to my last £70-80 so wanted to find out the opinions of you guys, which PSU (if indeed it is a PSU issue) to get.

The two that I have had my eye on this afternoon are :

Coolermaster GX 750W PSU - http://www.ebuyer.com/200490-coolermaster-gx-750w-psu-rs750-acaae3-uk?utm_source=google&utm_medium=products

or the

OCZ MXSP Series 700W 80+ PSU Modular Single 12V Rail 135mm Fan SLI Certified - http://www.ebuyer.com/152008-ocz-mxsp-series-700w-80-psu-modular-single-12v-rail-135mm-fan-ocz700mxsp?utm_source=google&utm_medium=products

Any advice please?

Thank you in advance

  1. the down and dirty answer; get the OCZ, better quality.
  2. GX 750, my final Answer!. Tho the OCZ may be better to some people. I have seen many more rigs using the GX 750 instead and it seems to work great for them. for 70-80$ for a 750 watt. thats great.

    But..... If you don't plan to SLI in the future you can get by easily with a cheaper 650 watt. What country do you live in
  3. I think a Seasonic, Corsiar or XFX power supply would be much better than the OCZ.
  4. a 650 power supply is enough unless you are going to SLI:
    EXDISPLAY XFX Pro 650W £63.90

    Corsair TX 650W V2 PSU - 80plus Bronze Certified £66.99

  5. Thanks for replies guys,

    Sorry forgot to mention that I don't plan to SLI ever. Just the one card is sufficient for me :)

    And I'm in England.
  6. Would u say then that it is definitely a PSU issue?

    yes. that card can and will pull 271 watts.

    and to guesstimate your rig is pulling another 150 watts thats 421 watts that a low quality PSU can fail at.

    i know this experience may make you apprehensive but a single card solution like yours can be ok with a QUALITY 550 watt psu.
  8. You could try driver/removing reinstalling just to verify your situation. But yea amongst those 2 I would say go with the ocz psu. If you had access to Antec/Corsair/Seasonic (XFX uses Seasonic) try for those at around 5-600w. Cheers

    Hehe ye I was looking at it earlier from the very tunnel-visioned (and noobish) perspective of the amount of Wattage the better but having read up on a lot this afternoon I now know better than that!

    I remember buying that Trust PSU a few years back to power the 8800 GTS that I bought and I kind of had an inkling that I might've needed to update my PSU as well as the graphics card.

    I'll probably go for the Corsair one you linked as it's brand new rather than ex-display like the XfX. Shame I'll have to wait until Monday before I can get stuck in as had borrowed Dirt 3 and Crysis 2 from a friend and was looking forward to some gaming tonight once the kids were in bed.

    Cheers for the help :)
  10. The 570Watt Would Be Fine Actually, As Long As Its A Decent Brand.
  11. Just ordered the EXDISPLAY XFX Pro 650W £63.90 one for delivery Monday.

    Wish me luck! :)

    Thanks for all advice

  12. XFX Pro 650W came this morning and have been having fun this evening with Dirt 3, Skyrim and Crysis all ripped to the max on ultra.

    Cheers for help all of you.
