I'm considering upgrading my power supply just so I can have the peace of mind that my PC isn't over exerting itself. But I figure if I'm going to upgrade my PSU, I might as well plan for the future while I'm at it.
My current specs are:
Disk drive - Sony Optiarc DVD Burner with LightScribe Black SATA Model AD-7241S-0B LightScribe Support
Processor - AMD Phenom II X4 945 Deneb 3.0GHz 4 x 512KB L2 Cache 6MB L3 Cache Socket AM3 125W Quad-Core Processor
Motherboard - MSI K9A2 CF-F V2 AM2+/AM2 AMD 790X ATX AMD Motherboard
Video card - MSI R4890-T2D1G OC Radeon HD 4890 1GB 256-bit GDDR5 PCI Express 2.0 x16 HDCP Ready CrossFire Supported Video Card - OC Edition
RAM - OCZ Fatal1ty Edition 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 1066 (PC2 8500) Dual Channel Kit Desktop Memory Model OCZ2F10664GK
Hard drive - Seagate Barracuda 7200.12 ST3500418AS 500GB 7200 RPM SATA 3.0Gb/s 3.5" Internal Hard Drive
Monitor - ASUS VH226H Black 21.5" 2ms(GTG) HDMI Widescreen LCD Monitor
Case - NZXT Beta Series CS-NT-BETA-B Black Steel / Plastic ATX Mid Tower Computer Case
Extra fan - 120mm Antec Tricool LED fan
I could see myself in the future adding another hard drive, and possibly another disk drive. But more importantly I want the option of using two 4890 crossfire video cards. So my question is, would a 650w Corsair power supply be sufficient for these future upgrades? Is the 750w really worth the extra 20 or so dollars?
One thing I noticed is that the 650w only comes with 2 PCI connectors. However, video cards come with PCI adapters. The question is whether or not using a PCI adapter rather than a PCI connector straight from the power supply affects quality. Does it?
So what do you think? 650w or 750w? Why?
