Hello, I am planning to upgrade my graphics card from a GTX 550Ti to a ASUS HD 7870 2 GB (overclocked version). I'm npt planning on overclocking or running it on CrossFire.

Currently, I have a Antec 620 Watt High Current Gamer PSU. Now, I'm wondering if this is enough for my system?

My System
- Motherboard: ASUS Sabertooth 990 FX
- CPU: AMD FX-8150 (not overcloked)
- HDD: Seagate Barracuda (7200 RPM)
- GPU: ASUS HD 7870
- PSU: Antec High Current Gamer 620 Watt
- 1 Blu-Ray Drive
- Case: Antec Twelve Hundred

Thank you in advance.

Yes easily enough. You could get away with a 450W PSU if you really wanted to. You'll have plenty of room to overclock too. Be aware that most of Antec's PSU's have multiple 12V rails rather than just a singular one, so make sure you don't overload a 12V rail.
