Do I need a PSU upgrade?

Hello Tom's Hardware! I am planning on installing some new hardware to my PC. The computer itself is about 3 years old but the power supply was replaced last December. Here are the specs:

Lenovo 3000H 210

Antec Basiq 430W PSU

Currently installed:

-2.2 Pentium Dual Core
-Radeon HD 4650 1GB
-4GB Ram (2 sticks)
-WD HDD Caviar Blue 500GB
-6 total USB 2.0 ports, 4 currently used (3 dongles, 1 iPod)
-"OEM" fans and disk drive

Want to add:

-WD 500GB HDD Caviar Black

-Creative Labs SB0880 PCI Express Sound Blaster X-Fi Titanium Sound Card

-PCI Express to SuperSpeed USB 3.0 2-Port Expansion Card (NEC/Renesas Chipset) which will be connected to a WD 500GB USB 3.0/2.0 External Hard Drive

-Cisco-Linksys WMP54G Wireless-G PCI Adapter

-Extra fan

eXtreme Power Supply Calculator gives me a rating of 373W with ALL of the above listed. Would love to hear what you guys think. Also would appreciate any upgrade suggestions if needed.

    Are you sure you did that correctly? I ran through it real quick with 2 hard drives, 4 120mm fans and everything else you said. I even swapped the chip for a b3 Q6600 that uses more juice. It came to 343, I think you'll be fine. If your going to upgrade to a powerful gaming video card,then you might need an upgrade.

    No, I do not plan to upgrade the graphics card. I do game but nothing the card cannot handle. No overclock either, just a simple desktop. I ran the numbers again and same rating. I will take your word for it though, thanks for answering my question and peace of mind!
  3. Np, don't forget, that is total system draw while gaming, using 6 usb devices, and everything else, which you probably wont be doing concurrently, Good luck.
