Power supplies decision
Last night power outage broke down my PSU, Antec True power 650.
Looking to buy one today, came down to these two selection. 1) CORSAIR Enthusiast Series TX750 V2 (http://www.newegg.com/Product/Produc...82E16817139021) 2) CORSAIR HX series HX650 650W ATX12V v2.2 (http://www.newegg.com/Product/Produc...82E16817139012) I probably did some calculation wrong with the online calculators, my cpu power usage was only 327, yet can't run games smoothly. Gfx card is geforce 550ti, i5 2500k cpu 1 x 7200rpm hdd 1 x dvd write drive 8gb ram ddr3 Question: if I want to upgrade video card and another 4-8gb ram later on, would these two be insufficient? Thanks in advance! :) |
You don't need anything close to that powerful.
Kingwin LZP-550 would be your best option at $120. It's more capable than the HX650 and far more efficient than the TX750v2. Like wise, it costs about the same and you could easily go to a Core i7 3770K & two GTX 680's with it. |

Extra wattage is not going to make any difference(well some with OC...but in general) Like TT says, you can run any top end card on your rig with a good 550 watt. My amd 7970 OC with and old AMD cpu (150 watt) never pulls over 350Watts. :D |

That video card made me drool... One question: would you choose to have 1 really good video card or on top of my crappy 550ti I buy another decent one and do dual? Quote:
I definitely am glad I read those stickies because before this incident I was fooled by salesmen at fry's. |

SLI and crossfire is dependent on software. Some games do well, some don't. Optimized drivers always lag game roll outs... New cards are more efficient...by the time you think of buying a second card...you can buy a new one that is twice as fast and cost less, and uses less electricity to boot. Only go SLI if you want insane resolutions and high settings NOW. :D Not some time in the future, example; pushing 3 or 5 monitors for 3d driving or flight sim. :D |
Just go for a single card.

Single card, I highly doubt much attention is paid to making 2x550Ti's scale properly,

SLi scaling depends on the game in question, and very many games just don't handle it well at all. It also confuses auto-config software, which tends to just set things up based on single card performance anyway. I wish I had gone for a single really good card over a pair of more modest ones. |
Today only, you can get a 660-Watt SeaSonic SS-660XP for $109 and free shipping, with a MIR for a further $20 off. Promo code EMCYTZT3071.
If I was getting a PSU today, that's what I would get. |
